This invention relates to improvements in ventilators for motorvehicles.

The principal object of the invention is to provide an improvedVentilator adapted to be mounted at the to of a window of a vehicle,such as a close automobile, which will permit of the proper Ventilationof the vehicle through `the window when it is lowered for that purpose.

Another object is to provide a ventilator which will prevent entrance offoreign matter through the lowered window.

Another object is to provide a ventilator which will act as an eavewhereb tected area is provided on the win ow glass immediately'beneathJthe said eave, through which area the driver can see even during arain-storm when vision through the rest of the window glass isobscured., The eave also, by excluding foreign matters when the windowis lowered a few inches below the lower edge of the eave, admitsof theproper ventilation of the cal-. dur1ng ram-storms and gives the driver aclear vlew through the o ened window.

A urther object is to provide a transparent ventilator which will notlessen the available transparent areaof the window even when the vehicleis on an inclined or a consideration of the following specification andaccompanying drawings, wherein Fig. l is a fragmentary side elevation ofa. vehicle showing the window and door equipped with my ventilators. 4

Similar reference characters are used to designate like elements in allthe views.

In Fig. 1, an automobile body 10. is shown (fragmentarily) which body isprovided with the usual door 11 and window 12, each of which may beprovided with one of my ventilators hereinafter described. Thel vehicleis provided with a windshield 13, which may be opened for purposes ofventilation, as may also the cowl ventilator 14.

As shown more particularly in Figs. 2 and 3, the ventilator comprises aglass 15,'whi`c'h is supported at each end by a bracket indi- 585 cated,general-ly, by numeral 16. The brackets 16 com rise outer `bracketmembers17,- shown in etail in Fig. 4, each of which members ispreferably formed of sheet metal, and is provided with a front ilange 18and lower flange 19. A-second bracket member 20, shown in detail 'inFig. 6, has an upturned flange 21 whichis disposed in parallel relationwith flange 18 when memers 17 and 20 are in operative relation. As`shown in Fig. 2, bracket members 17 and. 20 are secured to the side orstile of the window opening b means of screws 16*- which pass throngregistering holes 17 and 20* in the bracket members. The holes 20'* ofmember 20 arev slightly elongated in the direction of a line forming anangle of 45 with the vertical, as shown inFxg. 6, for a purposehereinafter to be explained.

A resilient strip 23 referably formed of rubber, is shown in ig. 7,which strip is channeled to receive the end of a glass 15.

vThe channel is closed at the bottom, vas

shown, thereby forming a resilient support 23l which protects the glassfrom contact l fill with ange 19 of the outer bracket member 17. As willbe seen in Fig. 2, the end of the glass rests-in the channel of themounting strip 23, which Strip is positioned within the channel formedbetween flanges 17 and 21. lt is desirable that bracket member 2O beadjustableto a slight extent to accommodate variations in glassthickness, etc., and for this reason the screw holes 20a in member 2Oare elongated, as above described. It will b'e' seen that the`elongation of` the holes ermits member 20 to be moved slightlydownwardly and to the right before screws 16 have been tightened,whereby said member 2O can be forced firmly against the resilientmounting strip 23. The diameter of the-screws is approximately the sameas the small diameter of the elongated holes, and since the forceexerted .by the compressed rubber strip 23 acts in a direction at rightangles to the plane of the flange 21 the likelihood of such force, orthe vibration of thel car displacing the member 2G is minimized.

he resilient mounting member or strip 23 is particularly'adapted forinstallation of a ventilator on a window having square corners, and theupper mitered end thereoi` coasts with a similarly shaped end of a topor upper resilient strip 2ato tightly 'close the corners of the window,as will be seen. The upper strip extends the full length of the glass15, is Vformed preferably with an upwardly projecting ange or rib 24e,which contacts with 'the upper frame of I* the window. This iange 24S?forms a seal between the glass 15 and the upper part of the window,whereby dust and rain, etc., are excluded. construction of strip 2eaccommodates the 'f tilator installation to variations in the width. ofglass and to any .slight irregularities in the portion of the windowframe with which tie strip contacts and also acts as a cushion for theglass.

Fign, a windenr ,lawine1 a somewhat rounded corner is shown providedwith my ventilator. rl`he l5 y be somewhat rounded at its upper corneconform te the shape of the windev? o; ne, but the bracket members and2n c.. the same as above described. l with. windows having rounded f fs,however, l f f enclosing prefer 'to use mounting the ends of the glasssuch ams a e illustrated in Figs. 9 and 10. This form of mountingStrip-2li is provided with a channel 251 for receiving the end of theglass, which channel 1s closed at the bottom, as shown in Fig. E), byend 25b for protecting the lower edge of the glass from Contact .withthe metal bracket. The curvature of strip 25 conforms approximately tothe curvature of the corners of the window. Since this curvature of thestrip, or of the window may vary somewhat in actual practice, the upperportion of the strip 25 is provided with a Hangs lslightly from thevertical position.

or rib 25 as shown, which, being, exible, will completely fill theWindow corners and form a tight t, said rib terminating adjacent the topof the particular bracket with which it is used. The top of the glass 15is provided with a resilient mounting strip ofthe form .previouslydescribed, the upper rib thereof co-operating with the upper por.- tionsof ribs 25c to form a sealbetween the top portion of the window frameand the ventilator, as will be seen. The strips 23 and 25 are roundedsomewhat on their back portions, whereby the strips can accommo date anyunevenness in the brackets, such as slight bends in the flanges thereofand adapts itself to the glass regardless of the angle of the bracket.

In Figs. 11 and 12, my ventilator is shown installed on a vehiclewindow, the frame of which is beveled, as shown at 26. The glass 15 hasits ends supported in rubber mounting members 27 which may be of eitherform previously described, depending on the shape of the window corners.The outer bracket member 28 having a flange 28El is secured by to themember 28, altho it may be riveted' or anchored otherwise. The upper ede of the glass 15 is provided with the resllient strip 30 havingY anupper rib 30 which projects into the groove 31, which the window glass32 enters when the window is closed. The lupper portion of strip 30 ispressed firmly against the lower surface of the window frame, wherebyforeign' matters are cxcluded, and a resilientl mounting is secured.inasmuch as bracket memberI 29 is wider' at the bottom than at the top,the same, when secured Ito the window, will be inclirpd e glass 15therefore used with this type of bracket will be somewhat longer at thebottom than at the top.

1n Fig. 13, the metal of the automobile body above the window isprojected downwardly into the window opening and is lll( folded back uon itself to form a Harige 33 Lacasse 3 in which the upper mountingstripv 35'is` rlhe member 36 thus hides the mounting strip 35 from viewand as a shield protects the same from deterioration.

The ventilator glass of the forms of'myinvention, above described, aresomewhat incllned, as shown, thus forming eaves or 1liwatersheds for thewindows with which the same are associated. During a rain-storm,

Afor instance, the 4ventilator will, if the Window is closed, maintain,a ystrip of the ywindow immediately below the lower edge of theyentilator free from rain.v If each win dow of the vehicle is providedwith a ventilator, the driver will have a belt of clear glass throughwhich unobscured vision Ato sides of the car can be had.` If thewindows,

equipped-with my' ventilators, are opened a few inches below the loweredge of the ventilator, rain will be excluded, a clear view through eachwindow will be had and the car can be properly ventilated. Inasmuch asthe ventilators do not lessen the lighting area or visibility throughthe windows to which they are attached, because the body ofthe-ventilator is of lass, the drivers view will not be obstructe by theventilators on the lower side of the car when the latter is on ajcrownedor banked road.

Motor vehicles, as commonly constructed,

. are provided with windshields, such as is shown diagrammatically at13- in Fig. 1. When the windshield 13 or cowl ventilator V14 is opened,air is admitted to the car and finds exit through the Vlowered window 12provided with my'ventilators. With the rear windows equipped with myventilators, this objectionable. feature in car ventilation can belargely overcome. To avoid theentrance of dust, the windshield and cowlventilator are closed and the windows in the car door 11 'areopened asare the rear windows 12 equipped with my ventilators. Air is admittethrough the windows in doors 12 and to some extent throu h' the cracksaround the'doors and passes om the car through the`- rear windows. Thedust which would pass through the windshield, if opened, is

thrown outwardly by the forward movement secured. The ventilatorprojects butfslight-` win ly beyond the side of the vehicle,preferablynot Jfarther outwardly than the door hinges. The ventilatorson the doors thus do not interfere with the iiull opening thereof, aswill be clear.

Although l have shown various modifications ot my improvements for thepurposes of illustration, it will be seen' that changes may be madetherein without departing from the spirit of the invention, and l do notwish 4to be restricted to the vmodifications here shown and described,except where limitations thereto appear in the appended claims.
